Vintage 1950’s light blue with big beautiful buttons dress

This vintage 1950’s cotton sundress looks absolutely stunning on a human, unfortunately the dress form isn’t doing it justice. I always felt like Marilyn Monroe when I wore this one! It is a simple and elegant sundress with big beautiful pearlescent buttons on the straps and down the left side, and a sweetheart neckline. The neckline has satin along the top. There is some discoloration in both armpits, which I am not sure how to remove. This dress is for a small person, even with my dress form as small as it can go at 33” it was a tight fit. I wore it when I was a size 5 with a 26” waist but see measurements. Waist: about 13” Armpit to armpit across the back: about 16”
